Compare the pathophysiology of chronic venous insufficiency and deep venous thrombosis.

Chronic venous insufficiency (CVI) is caused by a weakening of the vein wall that leads to pooling of the blood and changes in pressure within the vessels. This can be due to thrombosis, where a clot forms in one or more veins, obstructing normal flow and increasing pressure upstream. On the other hand deep venous thrombosis (DVT) occurs when a clot forms within a deep vein; this can occur as result either trauma or excessive immobility leading inadequate circulation throughout body particularly lower extremities. Unlike CVI which has very gradual onset symptoms and usually only affects superficial veins, DVT typically presents sudden pain/swelling with swelling lasting beyond 48 hours indicative blockage major vessel pathway restricting sufficient return blood into heart.

The patient factor I selected is obesity which could increase risk for both CVI and DVT as it reduces muscle tone around affected area resulting increased vascular engorgement causes localized inflammation further exacerbating illness severity. In terms diagnosing such disorder imaging techniques like ultrasound sonography would best tool determine whether abnormality present with current medical history also taken into consideration clearly illustrate underlying issue at play if indeed exists. Treatment recommendations might include medications dissolve clots over longer period time supplement regular exercise routine furthermore lifestyle modifications associated any existing comorbid conditions should prescribed simultaneously mitigate future potential issues providing successful symptom relief.
